报道了N-{4-{N-甲基-N-[2-羟基-3-(2,4-二氧代-1,2,3,4-四氢嘧啶-5-基)氨基]丙基}氨基-3-溴}苯甲酰基-L-谷氨酸二乙酯及其衍生物的简便合成方法. 分别以4-氨基苯甲酸乙酯和4-氨基苯甲酰基-L-谷氨酸二乙酯为起始物, 经甲基化、烯丙基化、溴羟基化、环氧化、开环、脱保护等反应首次合成了6个新型5-取代氨基嘧啶类化合物, 并通过1H NMR, 13C NMR 和MS对其化学结构进行了表征. 初步生物活性结果表明, 苯环侧链的L-谷氨酸酯部分是此类化合物抑制人重组二氢叶酸还原酶的必需结构.

A new practical approach to prepare diethyl N-{4-[N-methyl-N-(3-(2,4-dioxo-1,2,3,4-tetrahy-dropyrimidin-5-yl)amino-2-hydroxypropyl)amino]benzoyl}-L-glutamate and its derivatives has been realized from ethyl 4-aminobenzoate (4a) and diethyl N-(4-aminobenzoyl)-L-glutamate (4b). Six novel 5-(substituted)amino pyrimidines 911 were synthesized via methylation, allylation, bromohydroxylation, epoxidation, ring-opening, deprotection reaction and so on, and were characterized by 1H NMR, 13C NMR and MS techniques. The inhibitory activities against human dihydrofolate reductase of the compounds have been determined. The results showed that the bioactivities of the compounds were related with L-glutamate side chain.

Key words: 5-(substituted)amino pyrimidine, new anticancer agent, synthesis
